Well something like the algorthmic skeleton master-slave is useful.
See this: http://en.wikipedia.org/wiki/Algorithmic_skeleton.

Over your process library you might implement some skeletons for use at best.
I need something of higher level. I dont want to care everytime to
join each process.
Something like:
int four( 4 ), five( 5 );

pool_process_sample sample(3,out_queue); // three processes.
sample.set_function( boost::bind( add, four, five ) ) );
sample.start();
sample.join_all()

Here i can use the results on the output queue. This scheme can be
extended to have a map-reduce,
or an input queue as you like. In this case it is difficult have
syncronization errors, because it is all hidden.

Probally i missed some parts.
You could, if you want
provide a lower level and an higher level.
I will help you to test performance with my work 12 cores workstation :).

Cheers,
Giorgio.
